Oil-contaminated water and industrial oily wastewater discharges have adversely affected aquatic ecosystems human safety. Membrane separation technology offers a promising solution for effective oil–water separation. Thus, membrane with high surface area, hydrophilic–oleophobic properties, stability is candidate. Electrospinning, straightforward efficient process, produces highly porous polymer-based membranes vast area stability. The main objective of this study to produce polyacrylonitrile (PAN) cellulose acetate (CA) nanofibers using core–shell electrospinning. Incorporating CA into the shell enhances wettability. core PAN polymer improves electrospinning process contributes hydrophilicity–oleophobicity produced nanofibers. PAN/CA were characterized by Fourier transform infrared spectroscopy, field emission scanning electron microscopy, X-ray diffraction, surface-wetting behavior. resulting PAN/cellulose exhibited significantly improved demonstrating super-hydrophilicity underwater superoleophobicity, making them choice Various oils, including gasoline, diesel, toluene, xylene, benzene, employed in preparation mixture solutions. utilization as substrate proved be efficient, confirming exceptional efficiency, remarkable stability, prolonged durability. current work introduces an innovative single-step fabrication method composite nanofibers, specially designed This exhibits significant promise deployment challenging situations, offering excellent reusability efficiency nearly 99.9%.

Water-Induced Cellulose Nanofibers/Poly(vinyl alcohol) Hydrogels Regulated by Hydrogen Bonding for In Situ Water Shutoff

ACS Applied Materials & Interfaces, Год журнала: 2023, Номер 15(33), С. 39883 - 39895

Hydrogels have been widely applied to the water shutoff in oilfields due their excellent three-dimensional network and thermal physicochemical stability, it is still a huge challenge develop new hydrogels with simple preparation, low cost, high mechanical performance that can meet requirements of practical applications. Herein, we devised universal manufacturing method for regulating hydrogen bonds between poly(vinyl alcohol) (PVA) cellulose nanofibers (CNF) via water-diffusion action, thus fabricating physically tough PVA–CNF hydrogel situ shutoff. This allowed polymer chains strengthen molecular interactions polymers upon replacing (a poor solvent) regulate cross-linking structure, characterizing by nano-crystallinity domains fibrillar segments, which also accounted extraordinary elasticity, stretchability, toughness hydrogel. Further, obtained exhibited superb plugging performance, is, breakthrough pressure gradient could reach 71.56 MPa·m–1, surpassing all currently reported gelling agents. water-induced hydrogelation made well suited as agent may provide promising strategy fabricate mechanically robust smart materials projects processing, efficiency.
